Abstract

PROBLEM TO BE SOLVED: To simplify the mounting and dismounting of a nose pad by fitting the fixture of the nose and into a box formed at the front end of an arm and mounting the nose pad by utilizing the magnetic force of a magnet. SOLUTION: The arm formed to an approximately inverted U shape is brazed to a rim and the box 6 is brazed to the front end of this arm. A hole 7 is formed at this box 6 and the fixture 8 projected to the rear side of the nose pad 4 is fitted into the hole 7. The fixture 8 is embedded into the nose pad 4 and a spherical surface 9 is formed at the front end of the fixture 8. On the other hand, the hole bottom is formed to a spherical surface 10 as well. Since the size of the hole 7 is larger than the size of the fixture 8, a space remains therein and the fixture 8 is able to incline freely within the range of this space. The front end of the fixture 8 is formed as the magnet 11. The magnet 11 is attracted to the hole bottom of the hole 6 by the magnetic force. The box 6 having the bottom hoe of such spherical surface is easily manufactured by forging, sintering or casting.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nose pad mounting structure for supporting a front portion of eyeglasses.

[0002]

2. Description of the Related Art The nose pad for supporting the front part is attached to the glasses. If it is a resin eyeglass frame, the nose pad will be molded integrally with the front frame, but with a metal eyeglass frame, a box is formed at the tip of the leg extending from the inside of the rim, and the nose pad is formed in this box. A fastener that protrudes from the back of the pad is inserted and screwed.

However, when the nose pad is attached with such a structure, the screw loosens, sometimes falls off, and the nose pad comes off from the box. Further, although dirt adheres to the inside of the box, in order to remove the dirt, it is necessary to loosen the screw and remove the nose pad.

[0004]

As described above, the conventional nose pad mounting structure has the above-mentioned problems. The problem to be solved by the present invention is this problem, and provides a mounting structure for a nose pad that has a simple structure and is easy to mount and remove.

[0005]

The mounting structure for a nose pad according to the present invention is a structure in which a magnet is used to mount the nose pad using the magnetic force of the magnet. The magnet may be attached to the nose pad side, the box side of the leg tip, or both the nose pad side and the box side. It can be removed.

Here, the shape of the magnet is not particularly limited,
The nose pad which is fixed by a magnet can be structured so that its direction can be changed. Of course, unlike the conventional structure, it is not a structure that can be freely swung by screwing the fastener of the nose pad to the box, but by changing the direction of the nose pad stepwise or steplessly, I try to fit the position. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0007]

1 is a front view of a general spectacle frame, in which rims 1 and 1 are connected by a connecting member 2.
An outer wire 3 is brazed on the outer side of the inner wall of the inner wall of the inner wall of the wire, and a hook (not shown) is connected so as to be folded. A nose pad 4 is attached inside the rims 1 and below the connecting member 2. The glasses are to be supported by the nose pad on the front part of the glasses, but they do not have the structure tightened with screws as in the past.

FIG. 2 shows the details of the nose pad 4, the leg 5 having a substantially inverted U shape is brazed to the rim 1, and the box 6 is brazed to the tip of the leg. The box 6 is fitted with a fastener protruding from the back side of the nose pad 4. FIG. 3 is a specific example of the present invention showing a mounting structure of a nose pad, in which a hole 7 is formed in the box 6, and a fastener 8 protruding from the back side of the nose pad 4 is provided in the hole 7. It is inserted.

The stopper 8 is embedded in the nose pad 4, the tip of the stopper 8 forms a spherical surface 9, and the bottom of one hole is also a spherical surface 10. Since the size of the hole 7 is larger than that of the fastener 8, a space remains between them, and the fastener 8 can be freely tilted within the range of the space. The tip of the fastener 8 is a magnet 11, and the magnet 11 attracts the bottom of the hole of the box 6 with a magnetic force.

The box having a spherical hole bottom can be easily manufactured by forging, sintering or casting. Of course, when it is not necessary to change the direction of the nose pad 4, the bottom of the hole may be flat and the tip surface of one of the fasteners may be flat. Therefore, in this case, the leg 5 is bent to adjust the position and direction of the nose pad. In the embodiment shown in FIG. 3, a magnet is used on the side of the fastener 8, but it may be provided on the box side, or a magnet may be used for both the fastener and the box.

When both the tip of the fastener 8 and the bottom of the hole are spherical, the direction of the nose pad can be changed freely and steplessly. Since the nose pad may change its direction naturally due to sliding due to the external force acting, it can be formed by a polyhedron instead of both spherical surfaces 9, 10.

FIG. 4 shows a case where a polyhedron is formed instead of the spherical surfaces 9 and 10. The fixing tool 8 has a large number of polygonal flat surfaces 12, 12, ... A large number of flat surfaces 12, 12, ... Of the same size and shape are formed. The flat surfaces 1 are in contact with each other and are in contact with each other when the nose pad 4 is inclined.
The positions of 2, 12 ... Are displaced and the other flat surfaces 12, 12 ... Contact each other.

By contacting the flat surfaces 12, 12 ... In this way, the fastener 8 does not slide naturally, and when slipping, it overcomes the attractive force of the magnet and does not float from the bottom of the hole. Since it does not occur, some resistance occurs. As described above, the attachment structure of the nose pad according to the present invention has a structure in which a magnet is used for fastening, and the following effects can be obtained.

[0014]

The present invention is one in which a nose pad pad fastener is fitted in a box provided at the tip of a leg, and the nose pad pad is attached using the magnetic force of a magnet. It will be very easy. And since it does not have the conventional screw tightening structure, the screw will not loosen and the nose pad will not come off from the box, and it can be easily removed to wash away dust and dirt adhering to the inside of the box.

Although it is a mounting structure using a magnet, if the tip of the fastener and the bottom of the hole of the box are formed as spherical surfaces, the nose pad can change its direction. If is composed of a polyhedron, the direction of the nose pad will not change by itself.
